An 11-year-old girl showed in with no neurological impairments and an eight-month history of worsening scalp swelling. On closer inspection, a solid bulge looked to be coming from the frontal bone. The general and systemic exams produced normal findings. On MRI, a subgaleal component of a well-defined lytic lesion in the left fronto-parietal bone was seen. The patient had surgery, during which the tumour was excised and the patient's skull was rebuilt. On histological examination, a bone-derived monomorphic small round cell tumour was seen penetrating the subcutaneous tissue. After an immunohistochemistry test demonstrated widespread immunopositivity for MIC-2 in tumour cells, the final diagnosis of Ewing's sarcoma was made. Without experiencing any symptoms, the patient was monitored for three months. This study's main conclusion is that children and young adults with lytic lesions of the cranial bone should be tested for Primary Ewing sarcoma.
